The Internship Activities Tutor plays a significant role in both initial and in-service teacher training, not only by fostering disciplinary competencies but also by supporting their professional development. International research has highlighted that, in many cases, training initiatives aimed at teachers' professional development prove to be ineffective and inadequate in promoting improvements in teaching practices for teachers in training, with repercussions on students
Within this framework, this contribution presents a project proposal for a mentoring training program designed for Indirect Internship Tutors (Ment-TTi). The program aims to promote essential mentoring skills to guide the professional development of future teachers and teachers in training within the Single-Cycle Master’s Degree Program in Primary Education Sciences, Initial Teacher Training Programs, and the Specialization Course for Support Activities.
